Control method, control device and processing apparatus

Abstract

The control circuit controls the plotter provided with the feeding means for feeding out a roll paper and the processing means for processing the roll paper which is fed out by the feeding means. The control circuit includes the feeding control section which controls the feeding means so that, before the processing means starts processing on one page of the roll paper, a plurality of pages including the one page is fed out in advance and then, the page having been fed out in advance is pulled back and retreated at a position on an upstream side with respect to a processing position of the processing means, and the processing control section which controls the processing means so that processing of the one page is started when an elapsed time of the one page having been fed out in advance has reached a predetermined stand-by time.

The invention claimed is: 
     
       1. A control method for controlling a processing apparatus provided with a feeding means for feeding out a processing medium in a sheet shape and a processing means for processing the processing medium having been fed out by the feeding means, the control method comprising:
 a feeding control process which controls the feeding means so that, before the processing means starts processing on one processing range of the processing medium, a plurality of processing ranges including the one processing range is fed out in advance and then, the processing range having been fed out in advance is pulled back and retreated at a position on an upstream side with respect to a processing position by the processing means; and 
 a processing control process which controls the processing means so that processing of the one processing range is started when an elapsed time for the one processing range having been fed out in advance reaches a predetermined stand-by time, 
 wherein the processing apparatus is a friction type cutting plotter, 
 the processing medium is a paper in the sheet shape, 
 the processing comprises, while pressing a cutting edge of a cutter of the processing means against the paper, feeding out the paper in an X-axis direction and simultaneously moving the cutter in a Y-axis direction to cut out a form directed by processing data from the paper, and 
 the processing data comprise CAD (Computer Aided Design) data stored in a memory section of the processing control means. 
 
     
     
       2. The control method according to  claim 1 , wherein, in the feeding control process, the feeding means is controlled so that the processing range having been fed out in advance is pulled back and retreated in a slackened state without being folded at the upstream position with respect to the processing position of the processing means. 
     
     
       3. The control method according to  claim 1 , further comprising a measurement process in which an elapsed time after the processing range is fed out in advance in the feeding control process is measured for each of a plurality of processing ranges having been fed out in advance,
 wherein, in the processing control process, the processing means is controlled so that, for each of a plurality of the processing ranges, when the elapsed time for a corresponding processing range reaches the stand-by time, the processing for the corresponding processing range is started. 
 
     
     
       4. The control method according to  claim 1 , further comprising a first setting process in which a user sets the stand-by time,
 wherein, in the processing control process, the processing means is controlled so that, when the elapsed time for the corresponding processing range reaches the predetermined stand-by time set by the user, processing on the corresponding processing range is started. 
 
     
     
       5. The control method according to  claim 1 , further comprising a second setting process in which number of processing ranges fed out in advance in the feeding control process is set by a user,
 wherein, in the feeding control process, the feeding means is controlled so that the processing ranges are fed out in advance by the number of the processing ranges set by the user. 
 
     
     
       6. The control method according to  claim 1 , further comprising a third setting process in which a length of the processing range fed out in advance in the feeding control process is set by a user,
 wherein, in the feeding control process, the feeding means is controlled so that the processing range having the length set by the user is fed out in advance. 
 
     
     
       7. A processing apparatus comprising:
 a feeding means which feeds out a processing medium in a sheet shape; 
 a processing means which processes the processing medium which is fed out by the feeding means; and 
 a control device comprising: 
 a feeding control means which controls the feeding means so that, before the processing means starts processing on one processing range of the processing medium, a plurality of processing ranges including the one processing range is fed out in advance and then, the processing range having been fed out in advance is pulled back and retreated at a position on an upstream side with respect to a processing position of the processing means; and 
 a processing control means which controls the processing means so that processing of the one processing range is started when an elapsed time of the one processing range having been fed out in advance reaches a predetermined stand-by time, 
 wherein the processing apparatus is a friction type cutting plotter, 
 the processing medium is a paper in the sheet shape, 
 the processing comprises, while pressing a cutting edge of a cutter of the processing means against the paper, feeding out the paper in an X-axis direction and simultaneously moving the cutter in a Y-axis direction to cut out a form directed by processing data from the paper, and 
 the processing data comprise CAD (Computer Aided Design) data stored in a memory section of the processing control means.
